Why Choose the ABB OFAA000GG20 20A gG HRC Fuse Link?
The ABB OFAA000GG20 is a 20 A DIN-type HRC fuse link designed for general-purpose protection of low-voltage electrical circuits. With a gG full-range fuse characteristic, NH size 000 construction and a rated voltage of 690 V AC, it provides protection against both overload and short-circuit currents in suitable electrical distribution and industrial applications.
Unlike partial-range motor fuses, the gG utilisation category provides full-range protection for conductors, cables and compatible electrical equipment. The OFAA000GG20 combines this protective characteristic with ABB's compact DIN-type HRC construction, making it suitable for installation in compatible NH fuse bases and switch-fuse equipment.
This exact ABB OFAA000GG20, ABB order code 1SCA022661R8760, has a rated current of 20 A, a rated voltage of 690 V AC, NH000 fuse size and dual indication. Its rated power loss is approximately 2.4 W.
